This article is from 2012 and is very outdated. The "famous 9 lines" are not being contested anymore. Google lost that case. The current trial is about whether Google's copyright infringement constituted "fair use".
I was also surprised to see this here. It needs a (2012) tag in the title at the very least, as this is not what is being litigated right now.
"tag" is apparently not the correct word. I was downvoted for using the same term to point out the same thing for another article recently. No idea what the "correct" word should be though.
Maybe you weren't downvoted over the terminology. Putting the year in titles isn't required if it's an evergreen article (i.e., not news, not timely).
Interesting, thanks that's something I hadn't considered.
